l IMPRO'VEMENT IN ELEVATQ'RS FOR RAISINGAND STAG-KING STRAW.

The Schedule referred to' lnthese Letters Patent and making part of the same.

To all'whomz't may conce-rn Improved Elevator for Raising and Stacking Straw, Hay, and other similar 1substances and do hereby declare that the following description, taken in connection with the accompanying drawing, hereinafter re- .ferred to, forms a full and exact specification of the same, wherein I have set forth the nature and prineiples of my said improvement, by which my invention may be distinguished from others of -a similar class, together with such parts as I vclaim and desire to secure by Letters Patent; kthat is to say- One part of my invention consists, firstly, in providing, underneath the main irough of the .'elevatol', a second trough, through which the straw or sheatl' carriers, after turning over the top roller, are made to pass in their downward passage, whereby the saidV carriers are prevented from drawing the sheat orstraw down again.

Another part oi' my invention' consists in providing the main trough with a joint at or about the middle ot' its length, so that the upper part can be folded down over the lower part, and thus the elevator beren-- dered more compact for transport. When opened out, the joint oi' the trough is held secure Aby av catch or other fastening.

Another part of my invention has reference to the mode ot rais'mg and lowering the main poles yand trough, and the mode ot connecting the former to the latter. The main poles are stayed o r trussed at the sides by means of tensionrods, .and are arranged to turn, at or nea-r their lower ends, upon pins fixed to uprights carried by the framing. .lo the lower ends oft-hc poles are fixed toothed wheels or quad- 1 trough', the rails vbeing made to pass between the uprants, in gear with which are piuions, actuated through suitable power-increasing gearing by means of winch-handles. The upper ends ofthe poles (which are attached together by a transverse bar or rod) are connected, in such a manuel', to the upper end of the trough,=either by means ot' rails on the sides of the latter, fitting between anti-friction rollers fixed to the former, or by 'ot-her suit-able known sliding connections, -that the poles, iu being raised by the before-mentioned gearing, raise the upper end of the trough, and at the same time slide along the By this means either the entire trough Amay be vraised or low.- ered to any angle, orthe upper partmay be turned over onto the lower part, by the before-mentioned hinged joint. Y

Another part of my invention consists in providing anti-friction rollers in the main trough, for the chains of the carriers to pass over, in order to prevent the carriers from rubbing against the .guides to such au -extent as is at present the case.

'Another part of my invention consists in providing the front incline trough with endless chains, traveling over wheels, in order to prevent the straw or hay from lodging either at the sides or the end of the receiver.

On the accompanying drawing is shown my beforedescribed improved elevator.

.Figure 1, Sheet I, shows a side elevation;

Figure 2, Sheet II, .shows a plan; and

Figure 3, Sheet Il. shows an end eleva-tion otA the same.

The main trough A A' is divided in its length at a, the two parts being connected together by hinges, B,

.at the top ot' the trough, so that the upper part, A',

ot' the trough can be turned over onto the lower part, Afasshown in dotted lines in Iig. 1.

When opened out the ltwopartsi ot the trough are secured in that position by links or catolica-O, under down again..

-The main trough A A' turns, as usual, upon a fixed axis at its' lower end, and is raised or' .lowered into any desired position by means ol the supports or poles G turning at their lower ends, on strong pins, H, iixed to the uprights I of the carriage I', the upper ends ot' which poles are connected to the part A' of' the trough by yfitting with anti-friction rollers, K K', against angle-iron rails', L, fixed to theside of the per rollers, K, and tlie lower one, K'.

These rollers are carried by cheeks, M, capable or' turning upon a rod,.N, which ties the two poles G together, and it will bc seen that, as the'polcs are raised into the position shown in dotted blue lines, the rollers K K', while raising the trough, pass down along the side rails L, and at theisame time turn, with -thc cheeks M, upon the tie-rod N. -'lhe trough may by this means either be raised into any desired position, or the part A may thereby be turned 'right over onto A, as before mentioned.

For effecting the raising andlowering of the poles, these have fixed thereto 'toothed wheels, O, in gear with which is suitable powcr'incrcasing gearing, P, turned by winch-handles, Q.'

The poles are stayed laterally by means of tensionrods, R, secured to the sides of the toothed wheels O, as shown in iig. 1.

The front incline (or feed) troughv S is also provided with endless-traveling chains, T, passing round pulleys, U, at the top ofthe trough, and round other pulleys on the same shaft, V, that carries the pulleys of the carrier-chains to the main ftrough, and which is driven by thepul1ey and belt W.

VX X are anti-friction..rollers, Vprovided in the trough A A', over which the chains of the carriers pass, as before mentioned. Having thus described the nature of my invention, and in what manner the same is to be performed, I wish it to be understood that I do not limit myself to the precise combination of the several parts thereof', as shown in the accompanying drawing; but

1. A vsecond troughbeneath the main trough, substantially as and for thepurposes set forth.

2. The main' trough, when jointed at or about the In 'testimony whereof, -I have signed my name to this specification in the presence of two subscribingl witnesses this 19th day of April, 1870.
